Application May 28, 1942, Serial No. 445,105

2 Claims.

This invention relates to an improved apparatus for fabricating base material for corners employed in building construction.

In connection with the manufacture of siding simulating masonry or the like construction such products are usually manufactured having as a base fiber composition board or the like.

Siding products made in accordance with my copending application Serial No. 416,572, filed October 25, 1941, are generally composed of a base of ber insulating board or equivalent material. Generally on at least one face of such board is applied a coating material which may be asphalt or other bituminous substance. It is generally preferred that the coating have granular material embedded therein. When using such material, it is necessary in order that a pleasing appearance may be had, that there be provided corner members which are preformed, since it is difficult to obtain satisfactory corners 'by unit panels at a corner. v

One object of this invention is to provide a novel apparatus for producing a liber board or like base which can be utilized for making preformed corner members.

Another object of the invention is to provide an apparatus for grooving a fiber board which is to be employed as a base for corner building member.

Other and further objects of the invention include refinements of construction and operation, and will appear during the course of the following specification. Referring to the accompanying drawing wherein:

Figure 1 is a side elevational view with parts broken away of a corner fabricating apparatus;

Figure 2 is a left end view of the apparatus shown in Figure 1;

Figure 3 is a view of the preferred form of advancing rolls;

Figure 4 is a partial sectional view of the grooved portion of the corner base material;

Figure 5 is a partial sectional view of an edge side ci the corner base material with the V grooved portion broken away.

In making corners of the class shown in my application above indicated, vit is generally preferred that ber insulation board be employed as the base material. The base material for corners are grooved as shown in Figure 4 of the drawing and then the surface opposite the grooved side is treated to simulate masonry construction. The surface treated base material is then bent and secured in the 'bent position to form a corner construction material.

The apparatus generally is indicated by numera] Ill and includes a suitable supported means or table upon which are mounted feed rolls 22 and 23. The rolls 22 and 23 are geared together for simultaneous rotation by means of gears 25 and 26. The feed rolls are driven from a suitable source of power such as motor I8. As shown in Figure 3 the rolls are provided with knurled surfaces and the roll 23 has a rib or raised portion 2-4 about the middle portion. The rib 24 may be so constructed that it can be removed and a rib of a different width employed.

Secured to the table and extending longitudinally thereof is a bar or hold down means I6. The hold down means I ii is provided with ngerlike spring members Il for holding the board against the table while it is being advanced and grooved.

For grooving the corner material while it is being advanced, cutting means I2 and I4 which may be saws or revolving knives are used. The cutting means are driven by motors II and I3 and the angle of the groove to be made by the cutting means can be controlled by the adjusting of the angle of the motors I I and I3 on their respective supporting brackets. The motors II and I3 are adjustably supported on an adjustable arm of stands 2| which stands are mounted on table top I9.

Fiber board I5 of the desired length is fed to the apparatus I0. The board enters the apparatus and passes between rolls 22 and 23. As the board I5 passesl between the rolls 22 and 23 the rib 24 compresses the surface of the board as shown in Figure 4 at 29. The board I5 as it is advanced over table top I 9 is held down by the fingers I1 which are carried by member I6. As the board is advanced across the table top I9 the cutting means I2 and I3 preferably grooves the board so that the vertex of the groove is opposite the depressed portion 29 (see Figure 4).

The base material after being grooved and the face opposite the grooved portion being compressed may have one face coated with a suitable mastic material and then granular material spread over the mastic material and pressed extending longitudinally of the table and secured to the table near the rolls, and flexible fingers carried by said bar for holding down the board While the board is being advanced and grooved.

2. An apparatus of the class described comprising, a table, a pair of cooperating rolls mounted on said table near one end thereof for advancing fiber board, a circumferential rib about the middle portion of one roll for compressing one surface of the board while being ad- Vanced, a plurality of adjustable cutting means supporting stands mounted on the table, an adjustable cutting means mounted on each of said stands, said adjustable cutting means adapted to V groove the board opposite the compressed portion While being advanced, a, bar extending longitudinally of the table and secured to said table near the rolls, and flexible means carried by the said bar for holding the board down 15 While being advanced.
